Decide · Level 1 · Scene 0
A single cell became you, and nobody told it how.
Watch it once. Nothing is added from outside. Nothing arrives with a plan. Every step below is done by copies of one cell, following rules.
Nothing was added from outside. No plan was delivered. Every step was done by copies of this one cell, following rules. Nobody wrote the rules down. That is your job.
The Rulebook
Each puzzle hands you a situation, lets you change one thing, and asks you what the rule is. It only accepts rules you could test. You already know every word you need.
Page one is blank.
Already know the logic? Level 2 replays these same ten puzzles with the real biology named: a switch becomes a gene, the holder becomes Twist1, the crowd becomes neural crest. Go to Level 2 →All ten puzzles are playable. Play them in order for the full story, one cell to a face, or jump to any one. Each ends with a rule you write in your own words.
